Does he like me?

How can I tell if this guy likes but here the thing he has a girlfriend because some of da thingz he does makes me wounder if he likes me.because 2day when I walkin out a class (he comes in this class everyday da He's here) he grabs da back of my bag and I go back and he sayz you almost fell I said yea I know and walked off and said come here I said no he said man why you always actin like that and I said because I can and im sitin here thinkin does he like me and im afraid to like him back because im afraid I going to get hurt again because im really tired of gettin hurt and like a couple of days ago he was tilckin me on my neck and I tell him to stop and move his fingers and he does it again what do you think?

I think he is a jerk if he has a girlfriend and he is flirting with you. If you don't want to get hurt then he is not the right guy for you. If he is flirting with other girls when he is with someone what makes you think he won't do it to you? Find someone better!
